On my 67 I am going to run manual disc brakes, my engine will have alum heads, intake, i updated the front of the engine to run an aluminum late model water pump instead of the stock steel pump. I am using a mini denso alternator, with .125" thick aluminum brackets. Also using an aluminum and plastic M body master cylinder, and an aluminum radiator. I'd love to run one of those lightweight modded borgeson GM power steering boxes. I dont have the coin so its not happening. Anyhow this removed a bunch of weight. 340 torsion bars can also be found in 318 cars with factory A/C mopar installed them because of the added weight of the A/C
